Implement Nesbox in Blog

Question

I wanted to use the nesbox browser emulator in a blog using an external address.

According to the HTML code provided by the developer the code only takes a chunk of the address. Follow the example of excerpt from the developer’s code to attach the emulator to an html page:

var resizeOwnEmulator = function(width, height)
{
    var emulator = $('#emulator');
    emulator.css('width', width);
    emulator.css('height', height);
}

$(function()
{
    function embed()
    {
        var emulator = $('#emulator');
        if(emulator)
        {
            var flashvars = 
            {
                system : 'sega',
                url : '/roms/Flappy Bird (PD) v1.0.gen'
            };
            var params = {};
            var attributes = {};

            params.allowscriptaccess = 'sameDomain';
            params.allowFullScreen = 'true';
            params.allowFullScreenInteractive = 'true';

            swfobject.embedSWF('flash/Nesbox.swf', 'emulator', '640', '480', '11.2.0', 'flash/expressInstall.swf', flashvars, params, attributes);
        }
    }

    embed();
});

This code is to be made available at an internal address, but by using an external server I put the full address (example: 'http://exemplo.com/nome/flash/nesbox.swf') and the emulator even shows on the page, but the ROM does not load correctly, I believe because the other files (snes.swf, for example) that make emulation of the emulator platform are not recognized in the folder I created on the external server.

Anyone who knows this emulator has any idea what it is possible to do to run the emulator from an external address?
